TO JAMES H. HOLDEMAN, OF FAIRFIELD, NEBRASKA.

WH lFFLETREE-HQOK.

' zen of the United States, residing at Fairfield, in the county of Clay and State of Nebraska,

have invented certain new and useful Improvements in Whiffletree-Hooks; and I do hereby declare the following'to be a full, clear, and exact description of, the invention, such aswill enable others skilled in the art to which it app'ertains to makeand use the same.

A is one end portion of a whiffletree or other similar draft device, such as a swingletree or'doubletree.

B is a socket which fits over the extreme end portion of the whifiietree and which is secured to it by one ;or more screws 6 or other approved fastening devices. The socket is preferably conical and C is a narrow bar or blade which projects from one side of the socket: and which is secured to the whiffie- 7 tree by screws or other fastening devices 0.

- D is a spring-chamber formedcrosswise of the so cket and at its smaller end. One end portion of this'spring-chamber is provided With an end (1, having a guide-bolt d, which is preferably rectangular. This end portion of the spring-chamber projects over the end is slidable in the guide-hole d.

of the socket, and E is a projecting lug on the spring-chamber next to the said socket.-

E is'a hook A nut F is screwed on the end of the shank e, and Gris a spring arranged in the spring-chamber between the end d and the nut. A washer g is arranged between the spring and the nut; but this washer may be dispensed with if the Specification of Letters Patent. Application filed November i3,19o5. Serial No. 287,072.-

This invention relatesto hooks for'whiffle I chain in engagement provided with a shank which,

- Patented Oct-23, 1906.

nut is sufficiently large to afford a'good bearing-for'the end of the spring. The point of the hook is provided It, and the point of the hook and its said proections are normally held in contact with the lug E, so that it is impossible for the chain to become disengaged from the hook when the parts are in drawings- When the load is being drawn along, the spring allows the shank of the hook to slide to 'a limited extent in the spring-chamber, and

the hook can be moved by hand to place the With it. The lateral projections on the point of the hook also revent the chain from sli ping, and they a 0rd an extensive surface or engagin with the edge of the lug. The narrow b ade is arranged on the opposite side of the socket from the hook and renders the connection of the socket with the whiflietree very strong and firm and enables a short socket to be used.

What I claim is- 1. The combination, with a socket forengaging with the end of a whiffietree and having a means for securing the said parts to the whiffletree, and a spring-supported hook slidable in a guide crosswise of the said socket and projecting on the opposite side of the socket from the said blade.

2. The combination, with a socket for engaging with the end of a Whiflietree, said socket having a spring-chamber arranged crosswise at one end of it and provided with a projecting lug adjacent to the said socket, of a hook provided with a shank which is slidable in the said'spring-chamber, said hook ASSIGNOR or TWO-THIRDS the position shown in the projecting blade at one side of it, of

with lateral projections crosswise at one end of it and provided with hook in contact with the said end of the chainan end having a guide-hole, of a hook proher. :0 vided with a shank which is slidable in the In testimony whereof I have afhxed my said guide-hole and which projects through signature in the presence of two Witnesses.

the said spring-chamber, a nut on the end of WILLIAM TRUE. the said shank, and a spring arranged in the Witnesses: said chamber between its said end and the said J AS. M. LoVELL,

nut and normally holding the point of the D. F. FISHER.
